Using Segue Manually

问题 I need to create two Segue's from the same button, and then I want to programatically choice which one to use based on device orientation. The problem I'm having is that you can only seem to create one segue from a button to another view so when I add the second one it just changes the first. How do you add a segue that either isn't linked to a button etc so I can do programatically or how are you supposed to do this. I want to have two views that get dynamically picked based on orientation

问题 I am building an app for the first time using Storyboards. I have a scene which I would like to have open another scene when there is a long tap on a particular button. I am able to add the UILongPressGestureRecognizer with no problem, but I can't figure out how to have that gesture be the segue to the other scene. Doesn't seem to matter what I Ctrl-Drag, nothing works. Am I missing something obvious? Thanks, Ken 回答1: You can control-drag from your first controller's window to your second

问题 I just ported my project over to Swift 2, and everything is working great - except that even the most simple segues have no back button. Here is the prepare for segue function that I am using: override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { // Get the new view controller using [segue destinationViewController]. // Pass the selected object to the new view controller. if segue.identifier == "showExercise" { if let nav = segue.destinationViewController as?

问题 Within my viewDidLoad I would like some custom code based upon the previous controller. How can I access the segue source controller or the previous segue identifier in the destination controller's viewDidLoad to handle this? 回答1: There is no way to get a reference to the segue that created you. You could create a property (sourceVC in my example) in the destination controller, and assign self to this property in the prepareForSegue method (in the source view controller): [(DestinationVCClass

问题 I've currently have an iPad app with a UIToolbar containing two UIBarButtonItems, each of which is connected to a popover segue. When the user touches either of the UIBarButtonItems, the popover is created rather than toggled. This creates multiple, overlapping popovers. I've been able to close the previously created popover using the following code - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { // First close the preferences popover if it's open per Apple guidelines

问题 Depending on an XML return, I don't want the current segue to perform on UIButton touch. I know I can pick which segue I want to perform , but how to I make a segue not perform? Or at least not perform any of the available segues ? 回答1: If your deployment target is iOS 6.0 or later, you can override the -[UIViewController shouldPerformSegueWithIdentifier:sender:] method to return YES if you want to perform the segue and NO if you don't. If your deployment target is earlier than iOS 6.0, you

Dismiss modal, then immediately push view controller

How can I dismiss a modal and then immediately push another view? I am adding this code in a didSelectRowAtIndexPath: UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil]; ChatTableViewController *chatVC = (ChatTableViewController*)[storyboard instantiateViewControllerWithIdentifier:@"chatVC"]; [self dismissViewControllerAnimated:YES completion:^{ [[self navigationController] pushViewController:chatVC animated:YES]; }]; The modal view dismisses, but nothing happens after. Any ideas? You can't push a view controller into a view dismissed, if it's dismissed it
